| 测量原理 | 涡街 |
| 主要特点 | The flowmeter with a high pressure sensor, available as compact or remote version. Integrated temperature measurement up to PN 160 (Class 600). The specialist for applications with very high process pressure.
|
| 特点 | Highest mechanical integrity for flow measurement – special measuring tube material. High availability – proven robustness, resistance to vibrations, temperature shocks & water hammer. No maintenance – lifetime calibration. Process pressure up to PN 250 (Class 1500). DSC sensor made of Titanium (PN > 160 bar/Cl.600).
|
| Transmitter features | Convenient device wiring – separate connection compartment. Safe operation – no need to open the device due to display with touch control, background lighting. Integrated verification – Heartbeat Technology. Display module with data transfer function. Robust two‐chamber housing.
